ADVERTISING APPARATUS.

Application led January 8, 1923, Serial No. 611,501.

To all whom t may concern:

Be it known that `we WILLIAM GEORGE BARKEP. and FREDERICK RLANDO REAp,both subjects of the King of Great Britain, and both residents ofLondon, England, have invented certain new and useful ImprovementsRelating to Advertising Apparatus, of which the following is aspecification.

This invention relates to advertising apparatus and particularly toapparatus of that eneral kind in which a light-controlling e ement isadapted to rotate about .a prime source of light in order to causevarigated illuminations to pass across some form of display screenarranged in proximity.

The object of the invention is to provide means whereby such apparatuswill be rendered capable of producing more striking and 'varied effectsthan heretofore and to this end the invention consists in the provisionof one or more additional light-controlling elemcnts adapted to rotateindependently about the source of light and preferably about the firstlight-controlling elenient in order to produce a modified effect uponthe display screen.4

An embodiment of the invention is designed t0 produce the edect of aflying aeroplane silhouetted against a background of moving clouds isillustrated in the accompanying drawings in which Fig. 1, is nnelevation of a. transparent globe with my invention in place and Fig. 2is a detail of the construction which will nou7 be described. it beingunderstood that the Construction illustrated is susceptible of variousmodifications without departing from the scope. of the appended claims:-

Reterring to the drawing the same illustrates a frosted glass globe athe frosting being represented by the shading m--which in thisparticular case constitutes the display screenan electric lamp b mountedlhercwithin, a semi transparent cylinder o rotatable about saidlamp,land oppositely mounted templates (l in the formof acro planessilhouettes adapted to rotate both about said cylinder and said sourceof light.

ln the particular embodiment under con sideration the whole apparatus,with the exception of the templates d and the supporting means thereforis substantially identical with that described and claimed in thespecification of our prior British Patent. No. v178986. rlhus thecylinder c is. rotatablyv mounted upon a central wire pivot supported bythe lamp and carries air vanes in its upper endso that the risingcurrent of hot air consequent upon energization of the lamp causes saidcylinder to rotate. The supporting means for said templates are asfollows A. rectangular wire frame e the lowermost member of whichincludes a medial ring f and the uppermost member of which includes amedial support g for a pivot point It. is mounted upon the socket of thelamp.

the templates are made detachable from the arms.

The vanes in the member j are inclined in a different sense from thoseof the cylinder 0 so that the convection current of air rising from thelamp b will cause the cylinder and the aeroplane templates to` rot-atein opposite directions.

To assemble the apparatus the globe is lifted slightly from its seat thewhole unit comprising member 7' arms r and templates d is inserted byhand into the globe from beneath. An elongated hook is then insertedinto the globe from above and hooked into the ring Z whereupon the globemay be allowed to return to its seat and the said unit may be placedwith its bearing on the pivot point z, hy means of the hook.

ln the embodiment-J under consideration the cylinder c is so colouredthat when the lamp b is energised a cloud like edect is prolOG iectedfrom said cylinder on to the globe a.

That is, the cylinder is colored inppatches as indicated by o each patchthrowing a different colored shadow on the globe and as these shadowsrotate with the cylinder this gives the globe the appearance ofrotation. The effect produced by the templates al as will be understoodis that of aeroplane shadows or silhouettes so that the effect projectedupon lll@ the globe when the apparatus is in operation is that ofaeroplanes thrown into relief against a background of luminous clouds,the aeroplanes and clouds moving in opposite directions. l

Itis to be understood that the invention is by no means limited to theparticular construction described. For instance, the general arrangementof the display screen may follow that described in our prior BritishPatent N o. 162924 and We may if desirable vary the means for producingrotation of the two rotatable elements.

.What We claim and desire to `secure by Letters Patent is l 1.Advertising apparatus of the kind described comprising a source oflight, a eolored translucent cylinder rotatable on the axial plane aboutsaid light, an air vane pivoted in a cup shaped bearing.' in the axialplane of said cylinder and having a plurality of horizontal arms withdownward offsets, opaque figures secured to said arms, means for causingrotation of said cylinder and .figures by the heat from said lamp and afrosted shade enclosing said appara'tus.

2,. Advertising apparatus of the kind de scribed comprising a source oflight, a colored translucent cylinder with an air vane at its upper endrotatably mounted on its axial plane about said light, a second air vanepivoted in a cup shaped bearing in the axial plane of said cylinder,arms extending from said second vane, opaque figures secured to saidarms, a shade enclosing said apparatus, and an eyelet extending fromlsaid second vane 1n register wlth an aperture in said shade wherebysadvane may be positioned on said bearing.

.'Xdrertising apparatus of the class described comprising a source oflight, a translucent cylinder-With an air vane at its upper endrotatively mounted aboutsaid light, a second air vane rotatably mountedin the axial plane of said cylinder, a frosted globe enclosing saidapparatus, opaque figures secured to said second vane and arranged torotate close to said globe.

4. Advertising apparatusotl the kind described comprising a light bulb,a translucent cylinder with an air vane surrounding said bulb, a Wirefastened to said bulb and terminating in a point at the apex of saidbulb and forming a pivot for said cylinder, a wire frame secured to thebase of said lamp supporting a cup-shaped bearing in the axial plane ofsaid cylinder, a second air vane pivoted in said cup-shaped bearing andarms with figures secured thereto supported by said second vane.

5. Advertising apparatus of the kind described comprising a light bulb,a plurality of bearings in the axial plane of said bulb. a plurality oi'air vanes pivoted in said bearings and adapted to be rotated byconvection currents of air from said bulb, a frostcd shade surroundingsaid apparatus, opaque figures secured to one of said air vanes andarranged to rotate close to said shade, and a translucent cylindersecured to the other air vane.

In Witness whereof we afiix our signatures. WILLIAM GEORGE BARKER.FREDERICK ORLANDO READ.
